soon-ms. (min -2s) This invention relates to the treatment, of water with chlorine in liquid form for the purpose of sterilizing the water.

An object of this invention is to provide 'for handling chlorine solutions with safet and in such manner that the admission or'the. ch10? rine solution is Visible andrnay be controlled to a very fine degree. Anothervobject of this invention is to 'p'ro'vide an apparatus for introducing chlorine solutions into a stream of water in predetermined ratio to the quantity of water flowing in a suction lihle and so that for any givenquantity of water nowing in thesuction line a given weight of chlorine solution will be introduced. v a Another object of this inventionisto provide a liquid feeding device of the character referredto, which is of extremely simple construction inexfw pensive to manufacture; has nomoving parts and is automatic in its action. l

Another object of this invention is to provide a 'chlorinator made of glass and clay containers and hard rubber tubing and which will be resistant to the corrosive action of the chlorin and provide safe operation. v L I With the above and other objects in view, the invention will be hereinafter more particularly described, and the combination and arrange: merit of parts will be shown in the accompanying drawing and pointed out in the claims which form part of this specification, 7 j v4 Th drawing is a front elevation of the chl'oijiQ nator, the reservoir and the'flow visibility container being in cross-section. H V

In the illustrated embodiment ofthe -invention; the numeral 10 indicatesa bottle containing a reserve supply of chlorine solutionwhich it is desired to add in small quantities to the fluid passing through-a suction line H connected to a pump P.

Mounted below the bottle I is a reservoir or receiving vessel l2 having a liquid level l3 which is to be maintained constant. For this purpose the bottle Ill is supported in the inverted position shown in the drawing, with the neck M of the bottle extending into the reservoir and with the mouth I5 sealed'by the liquid therein.

As the liquid is drawn from the reservoir I2 its level is lowered. When the liquid level falls below the mouth l5, air passes into the bottle and liquid is permitted to flow therefrom until the level of the liquid in the reservoir reaches the bottle mouth l5 and seal it. t

Chlorine solution is periodically drawn from the bottle in, the flow of chlorine solution from the reservoir l2 controlling the flow of :chlorine solution from the bottle. The level eli ofvthe chlorine solution in the "reservoir. l2 iSLthuS, maintained constant' by theii'nverted bottle actiomu A'twoememb'er siphon tube comprisingia-short, er legfilfi and ailonger leg 1'61 is supported. above the bottle [0 and thereserv'oir 12 by meansoia transparent .container i1 .chaving a perforated i cover l8 in which .endiportion's of: the-said siphon tube members "are suitably recived in air-tight engagement. 1 i i i The container i?"is preferablyvmadeeof glass whereby itis resistant to corrosion; The con;- tamer I1 is mounted-man upright position onna bracket 19 at the upper end portion 'of a-frameAZQ which also supports the bottle it] and the reservoir l2 and forms a self-contained chlorinating unit;

The receiving end of thelower end 2! of the shorter leg 16 is submerged-in-the-reservoir I21 The upper end 22 of'the shorter leglB terminates in considerably spaced relation 'f rom the botton'i of the container l'l.- Tli'e'upperiie'nd 23 or the longer leg lefteri'riinates i-nslightly spaced relation from the-bottom of the container i1; The lower end'24 of the'longei' leg" [6 is connectedto the siictionline l'l. v In o eration, service water to be chlorinated; passing through the main-ll eausesa uction i i the leg Hi arid a; parish vacuum is formed in' the container H-wherb'y the liquid n the re er; voir I2 is caused tote sucked up and centered from the reservoir in the term ofvisibl rops 25; The dropsaeeumuiat at the bottem of the container H and mime-layer of chlorine liquid 26 1 on setse-5m of said container s'tififciiit to" immerse me nder the leg is" i said e6iiplate. 7 l

The visibly issuing drops 25 of the sterilizing liquid are at all times clearly seen through the glass container l? and thereby assure the user that the sterilizing apparatus is performing its duty, while correspondingly warning of accidental failure of proper operation.

, Apetcock or valve 21 in the shorter leg l6 serves for controlling the flow of the sterilizing liquid to a very fine degree. The chlorine solution is thus introduced in predetermined ratio in accordance with the water supply flowing in the suction line.

The bottle Ill is carried and held bodily in a crate 28 while the neck of the bottle is entirely without the crate. The crate maybe swpt'alner when a continuous-feeding anomalies ported in any suitable manner to the frame 28 such as by brackets 29 and bolts 36.

p The reservoir I2 is preferably a clay pot. The two members of the siphon tube may comprise Bakelite tubing and rubber hose having a degree of rigidity which will prevent collapse of same in service. V V i It will thus be seen that there has been provided a chlorinator which maintains the feed of chlorine for which it is set absolutely constant and uniform until it is reset to feed another amount.

In accordance with the patent statutes I have described and illustrated the preferred embodiment of my invention, but it will be understood that various changes and modifications can be made therein'without departing from the spirit of the invention as defined by the appendedclaims.

I claim:
